71. Temperature Specmanship And Selecting Power Inductors 10/6/2008
    How many datasheets have we, as engineers, reviewed and all of the data we need is there? Well, if your experiences are like mine, very few times if at all. And to compound the problem the data listed that pertains to your project was measured at a temperature not where you are planning to run your board. By Datatronic

73. Tutorial: Switch Mode Power Supplies And Their Magnetics 10/6/2008
    Many factors must be considered by designers when choosing the magnetic components required in today’s electronic power supplies. By Datatronic
74. White Paper: Transformer Design For Charging Defibrillator Capacitors 10/6/2008
    Generating high voltage by means of flyback topology is a common approach. Using the generated voltage to charge a capacitor for a high energy pulse are used in defibrillators, photoflashs, strobes and ignition circuits to name a few. The procedure outlined in this article is useful in the initial transformer design phase for charging a capacitor in a stated time. By Datatronic

    In today’s day and age the most often used topology for electronic power supplies is that of the Switch Mode Power Supply (SMPS), which is a major user of magnetics. In some applications the “older type” linear supplies are still used, but in the early 70’s SMPS came into being spurred by the development of faster switching transistors

78. Current-Sense Transformer Application Design Guidelines 4/28/2008
    The standard for precise current measurement in instrumentation and other high reliability equipment applications has been the current sense transformer. They are accurate, easy to implement, and reliable under harsh environmental and thermal conditions. In electronic systems applications such as switch-mode power supplies, current transformers are generally used for control, circuit-protection, and monitoring features. With the increasing availability of OTS (Off-The-Shelf) current transformers, a simple guideline can greatly help in the selection of proper and cost-effective components for many applications.

80. White Paper: Measuring Transformer Distributed Capacitance 4/28/2008
    This article is a general discussion of distributed capacitance, Cd, in transformers with emphasis on measurement. Capacitance in a transformer winding cannot be avoided. The voltage difference between turns, between winding layers, and between windings to core, create these parasitic elements. In general, part of the designers' task is to keep capacitance to a minimum. On rare occasions winding capacitance is increased to reduce ringing in switching transformers.
